Key Parameters

Substitute Part Grouping Explanation

The 71918-144LF qualifies as a direct functional substitute for the 10087119-144LF based on the following critical parameters:

Matching Parameters:

• Connector type, contact type, and gender (Header, Male Pin)
• Position count and row configuration (44 positions, 2 rows)
• Mating pitch and row spacing (0.100" / 2.54mm)
• Mounting method and termination (Through Hole, Solder)
• Shrouding design and fastening mechanism (Shrouded - 4 Wall, Latch Lock/Eject Hooks)
• Insulation material and flammability rating (Thermoplastic Glass Filled, UL94 V-0)
• Moisture sensitivity classification (MSL 1)

Differences:

• Product status: 10087119-144LF is obsolete; 71918-144LF is active
• Contact material: Brass vs. Phosphor Bronze
• Contact finish specifications: Gold (1.97µin) vs. Gold GXT™ (30.0µin) with Tin post finish
• Packaging: Tube (71918-144LF)
• Compliance certifications: RoHS Compliant and REACH Affected (71918-144LF)

Parameter Comparison

Engineering Selection Recommendations

The 71918-144LF is the direct equivalent for the obsolete 10087119-144LF. Both parts maintain identical mechanical and electrical interface specifications, ensuring pin-for-pin compatibility in board-level applications.

The 71918-144LF offers advantages for new designs and ongoing procurement:

• Active product status ensures continued availability and manufacturer support
• RoHS Compliant and REACH Affected certifications meet current regulatory requirements
• Enhanced contact finish specification (30.0µin gold with GXT™ technology) provides improved durability and contact reliability compared to the original 1.97µin specification
• Phosphor Bronze contact material offers superior spring characteristics and wear resistance relative to brass
• Tin post finish on the 71918-144LF provides enhanced solderability

For legacy system maintenance where the original 10087119-144LF is required, the 71918-144LF serves as a functionally equivalent replacement without design modification.

Frequently Asked Questions (FAQ)

Q: Are the 10087119-144LF and 71918-144LF mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (0.100" / 2.54mm), row spacing, position count (44 in 2 rows), mounting type (through hole), shrouding configuration (4-wall), and fastening mechanism (latch lock/eject hooks). They are direct mechanical substitutes.

Q: What is the difference in contact finish between these parts?

A: The 10087119-144LF features gold plating at 1.97µin (0.050µm) thickness on brass contacts. The 71918-144LF uses gold GXT™ plating at 30.0µin (0.76µm) thickness on phosphor bronze contacts with tin-plated posts. The thicker, enhanced finish on the 71918-144LF provides superior contact durability and lower contact resistance.

Q: Why is the 10087119-144LF listed as obsolete?

A: The 10087119-144LF has been discontinued by the manufacturer. The 71918-144LF is the active production equivalent and recommended for all new designs and replacement applications.

Q: Does the 71918-144LF meet current regulatory requirements?

A: Yes. The 71918-144LF is RoHS Compliant and REACH Affected, meeting current environmental and regulatory standards. The 10087119-144LF predates these certifications.

Q: Are there packaging differences between these parts?

A: The 71918-144LF is supplied in tube packaging. Packaging specifications for the 10087119-144LF were not provided in the technical data.

Q: Can I use the 71918-144LF as a drop-in replacement in existing assemblies?

A: Yes. The 71918-144LF is a direct functional equivalent with identical interface dimensions and electrical characteristics. No design modification is required.
